The Homelite 240 is a lightweight chainsaw with a 39.3 cubic centimeter engine. The chainsaw can run either a 16-inch or 18-inch guide bar. Originally manufactured in 1986, the Homelite 240 was built to run on nonethanol, high octane fuel. According to the Home Depot, owners may wish to add a gasoline treatment additive due to the ethanol found in modern gasoline. This allows the Homelite 240 to start and run more smoothly.
